Please accept this letter as my formal apology for what happened on on our last business dinner held on .01/28/2013..

It was not my intention to cause any damage or inconvenience. In retrospect, I believe the situation resulted from great tension and pressure I felt due to importance of this event. While this is by no means an excuse for my behavior, knowing the cause will help me guard against future mistakes.

Again, I am sorry for what happened. If you would like to continue this conversation, please feel free to call me at 00 000 000000. I look forward to hearing from you and putting this matter behind us.
